Description
Hyperdrive compatible and available in down swing and top swing versions, this front derailleur offers improved tyre clearance and better manoeuvrability. Shimano has also kitted out this model with Mega 9 Lite technology, which uses a refined front shifting system to deliver more reliable shifting performance on every ride. Technologies: Mega 9 Lite: Light pedalling with efficient drivetrain. Optimal gear ratio for each wheel size. The larger the wheel the more range needed in the cassette to maintain light pedalling. Refined front shifting system. Gear combinations specialised for each tyre size reduces the number of recovery rear shifts needed with front close gear ratio. Tyre clearance improved for better manoeuvrability. HG HyperGlide: The distinctively designed HYPERGLIDE sprockets incorporate specially positioned shift ramps and tooth profiles for improved chain control during shifting. Fast and responsive indexed shifting is the result. The HG cassette sprocket, which was developed for the MTB 10-speed system, underwent comprehensive optimization to achieve super-highly efficient shifting.
